Re: Compact Flash audio player?
 

Hi Matt,
I wish I spent more time reading up on the digital camera, instead
of arguing here. I bought the kids digital movie cameras that use both a
tape and memory card, and the TV DVD recorder that records a hundred
hours for later viewing, then burn to disk if they like, in hopes the
would begin to convert to disc. I have the same equipment, but the
thought of converting over a thousand hours of home movies is
overwhelming! At least I recorded my 8 mm.

Re: Compact Flash audio player?
 

Matt;

Actually, a 700 MB CD can hold only 80 minutes (give or take a couple
minutes) of music in CD Audio format:

http://www.pcguide.com/ref/cd/formatCDDA-c.html

Your 1 MB /minute estimate is a good approximation for 128 kbit mp3
format. Even though the sampling rate is high, I think the sample
size is smaller, and the mp3 compression discards a lot of aural
information.

When you are ripping the songs, you can choose a higher sample rate to
trade off size for higher quality. But with all the wind noise,
clanking and rattling going on in my jeep, standard mp3 quality is
fine to my tin ears.

Even at CD Audio levels, I wouldn't mind terribly having to swap out a
handfull of CF or SD cards on a trail. It would sure take up less
space in my console.

Did I mention how nice it would be to have music with no moving parts
to get fouled up with dust?

Re: Compact Flash audio player?
 

Your statement of how much space each minute of the different music
formats (CD and MP3) uses was a little off...

CD Audio is actually about TEN (10) MB per minute of music. Which is
why a CDR can hold 74 minutes of music or 700 MB of data.

MP3s, at 128kbps, take up 1 MB (960 KBytes to be exact) per minute. I
don't think 128kbps sounds good enough, though, so I rip at no less
than 192kbps (1.440 MB per minute). So, do a little math, and you find
that one 256 MB CF card will hold:

256 MB / 0.960 MB = 266 Minutes, or 4.44 Hours. Not bad at all.
256 MB / 1.440 MB = 177 Minutes, or 2.96 Hours. Still not too shabby.

So, the 256 MB CF card wouldn't be bad at all for you what you're
wanting. I just thought I'd make sure everyone understood the correct
sizes for these different mediums. Your mentioning CD audio is only 1
MB/s when it's actually 10 (probably simply a typo on your part since
your estimate of how much music playtime you would get out of the card
was near to the mark) was what made prompted me to post. Just so no
one else out there gets confused.

Ack. Brain fart.

OK, I meant 10mb/min.

Yes, I am an audio engineer. :-/
